The Siemens 3RK1911-0BD40 is a pre-terminated ECOFAST power connection line: seven conductors, each 2.5 sqmm, cut to a 10 m length and fitted with a HAN Q8/0 connector on one end. This is the ready-to-run cable you pull between an ECOFAST distribution box and a motor or actuator on the line — no field-wiring the connector, no guessing the strip length. The 7 x 2.5 sqmm cross-section handles the current draw of a small motor group or a multi-conductor sensor/actuator bundle in a single sheath.
Deployment context
This cable is built for the ECOFAST quick-connect system used in Siemens AS-Interface and motor starter networks. The single-side HAN Q8/0 plug means the box end is ready to mate; the unterminated end runs into the motor or distribution block, where you strip and terminate to the terminal strip. The 10 m length covers most panel-to-machine drops in a typical cell layout — long enough to route through cable tray, short enough to avoid coiling excess.
